Description
好ましい実施形態を参照して本発明を説明したが、当然ながら、特許請求された発明の本質と範囲を逸脱することなく、それらの形態および詳細における変化形および改変を作製することができる。このような変化形および改変は、本明細書に添付された請求項の権利および範囲内であるとみなされる。
［本発明の態様］
［１］
セメント押出し用モルタルに使用するための混合組成物であって、
ａ）２０〜９９．９重量％の量の、未加工コットンリンターから製造されたアルキルヒドロキシアルキルセルロース、ヒドロキシアルキルセルロース、および、それらの混合物からなる群より選択されるセルロースエーテル、および、
ｂ）０．１〜８０重量％の量の、有機性または無機性の増粘剤、垂れ防止剤、空気連行剤、湿潤剤、消泡剤、流動化剤、高性能吸収体、分散剤、カルシウム錯化剤、遅延剤、促進剤、撥水剤、再分散性粉末、バイオポリマーおよび繊維からなる群より選択される少なくとも１種の添加剤、
を含み、ここで、該混合組成物をセメント押出し用硬練りモルタル配合物に用いて、十分な量の水と混合すると、該配合物は、パイプ、レンガ、プレート、距離ホルダーまたはその他の物体の押出しのためのモルタルとして用いることができるモルタルになると予想され、ここで、モルタル組成物中の混合組成物の量は低減されており、得られた軟練りモルタルのひび割れの形成は、従来の類似のセルロースエーテルを用いた場合と同等か、または、それより低く、同時に、可塑化および／または押出し特性は、従来の類似のセルロースエーテルを用いた場合と比べて改善されているか、またはそれと同等である、上記混合組成物。
［２］
前記アルキルヒドロキシアルキルセルロースのアルキル基は、１〜２４個の炭素原子を有し、ヒドロキシアルキル基は、２〜４個の炭素原子を有する、１に記載の混合組成物。
［３］
